AEROPLANE.

Application filed July 12, 1923. Serial No. 650,998.

To all whom it may concern: 7

Be it known that I, JESSIE E. M. SEALE, a citizen of the United States,residing at Odessa, in the county of Pasco and State of.

novel and improved means for the propul sion of the same.

An object of the invention is to provide propulsion means for aeroplanesby means of which a large area of open space is-not required for properlanding or launching of the aeroplane.

. Another object of the invention is to provide means whereby theforward movement of the aeroplane is insured upon ascension of the planeto a predetermined height.

Other objects willappear as the nature of I the inventionis betterunderstood, and the' same consists in the novel form, combination andarrangement of parts hereinafter more fully described, shown in theaccompanying drawings, and clainied.

i In the drawings forming part of this applicatibn, like numerals ofreference indi gate similar parts in the several views, and

wherein:

Figure 1 i a top plan view of an aeroplane, constructed in accordancewith the present invention. Figure 2-is a bottom plan view thereof,

partly brokenaway.

Figure 3is a longitudinal sectional view of one of the wings takensubstantially upon line-33 of Figure 1, and

Figure 4-is a fra mentary I elevational view showing one of t e wings inrear elevation.

Referring more in detail to the drawings the embodiment of the inventionasshown 45. consists of a biplane having a fuselage. 5,

with wings 6 extending from opp'ositesides of its forward portion, andprovided with a'seat 7 at its forward end for-reception of the pilot,the tail portion of the fuselage bemg provided with the usual horizontalrud ders B and vertical rudders ,9 for controlling the course of travel.

' In accordance Wltl'l the present invention, the wings 6 are of hollowconstruction, a

shown in Figure 3, and have their forward driving the shaft 15, and theblower fans 13 edges formed as at 10 with a stream line effect, so as tooffer little resistance, while travelling through the air. These wingsare tapered rearwardly to a considerable thickness, so as to presentrelativel wide flat rear edges 11, whereby consi erable displacement ofthe air is had,-the rushing of which in behind the broad rear edges 11assists in the forward propulsion of the aeroplane.

The lower wall of each of the wings is provided with a substantiallycentral opening, in which is fixed the intake end of an angular airtube, 12, which extends for.- wardly toward the front edge of the wingwithin the latter as shown in Figure 3. Arranged Withinthe intakeportion of each of the tubes 12 is a blower fan 13, adapted to berotated for drawing air into its-tube l2- and forcing the same out ofthe forward end of said tube into the interior of the wing, and againstthe interior face of the forward portion thereof- Theblower fans 13 maybe mounted on a common shaft 14, extending transversely of the aeroplaneto ward and into the fuselage 5 where it is operatively connected toa'suitable engine 15.

' As shown in Figure 4, each of the wings is formed with a relativelylarge opening 1n the rear edge ,-11 thereof, which opening is normallyclosed by means of a door or'gate 16, which may be provided with aclosing spring 17.

In operation, the engine 15 is started for fix'edthereon. This causesthe air to be forced throu h the tubes 12 into the interior of each ofthe wings, and-against the forward portion of the same thereby buildingup an air pressure within the wings. This will result in causin g analmost direct as-' cension of the aeroplane until the pressure built upwithin the wings exceeds the strength of the closing springs 17. Whenthis takes place, the air pressure within the wings causes the gates 16to swing outwardly and downwardly to open position,- so that the airwill rush out of the'openings closedby said gates and will thereby'causeforward movement of the aeroplane.

' edges, and relatively wide flat rearledges,

' rerae ao Minor changes may be made therein, without departing from thespirit and scope of the invention as claimed.

7 Having thus described my invention,- what I claim as new, --and desireto secure by Letters Patent, is:

1. In an aeroplane, a fuselage provided with oppositely projectinglaterally extending ho low wings formed with openings in their rearedges, spring closed gates nor -mally closing said openings, and meansassaid rear edges having 0 enings therein, spring closed gates norma 1yclosing said openings, the lower walls of the wingsbein provided withopenings, angular air ta lies fixed in said openings and projectingforwardly therefrom in the interior ofthe the intake ends of said airtubes for forcing air through the latter against the interior surfacesof the forward portions of the wings and for buildinga pressure withinthe wings sufiicient to open said gates.

3. In an aeroplane, a ifuselage with laterally extending wings, saidwings being of hollow form with stream line front edges, and relativelywide flat-rear edges,

said rear edges having '0 enings thereini spring closed gates norm'a yclosing sai openings, angularair tubes fixed in said 0 enings andprojecting forwardly there-v 0111 in the interior of the wings, andblower elements positioned in the intake ends of said air tubes forforcing air through the latter'against-the interior sur faces of theforward portions of the wings and for building a pressure within thewings suficient to. open said gates, a motor" within the fuselage, and atransverse shaft operatively connected to the motor and said blowerelements.

In testimony whereof I afiix my signature.
